So heres the deal, had my truck for about a year now, and have always gotten terrible mileage.
normally between 230-280 MAX a tank, sometimes 180...

My truck was stock completely when I got it, added a 4 inch cat back exhaust, deleted the cat, and got an SCT Livewire.
Still ****.

Recently blew my heads apart, 4 valves got stuck open and bent the rocker arms.
So just spent $7690 to get it back.
Brand new heads, brand new gaskets, ARP headstuds, 155 RCD injectors, EGR blockoff with a bulletproof EGR, BullyDog CAI, SCT Livewire with Custom tunes from dfuser, 4.5 inch lift on some 35's, and also have a 3.5 inch downpipe sitting in the box waiting to be put on.
Anybody have any suggestions, tried ONE time driving normally and it didnt help at all.
